unit. Use only gage line sets which have a “Schrader”

depression device present to actuate the valve.

Charging an R-410A Unit in AC Mode with Outdoor

Temperatures Above 55° F

1. With the system operating in a steady-state, measure

the liquid refrigerant pressure (in psig) at the service

valve.

2. Measure the liquid refrigerant temperature (° F) at the

service valve.

3. For the temperature measured, determine the required

liquid refrigerant pressure from your units label or

charging charts (Figures 8 - 11, pages 13 - 14).

• Ifthepressuremeasuredinstep1isgreaterthan

the required liquid refrigerant pressure determined

in step 3, there is too much charge in the system.

Remove refrigerant and repeat steps 1 - 3 until the

system is correctly charged.

• Ifthepressuremeasuredinstep1islessthanthe

required liquid refrigerant pressure determined in

step 3, there is too little charge in the system. Add

refrigerant and repeat steps 1 - 3 until the system is

correctly charged.

START UP & ADJUSTMENTS

Pre-Start Checklist

The following check list should be observed prior to

starting the unit.

√ Verify the unit is level and allows proper condensate

drainage.

√ Verify the outdoor coil and top of the unit are free from

obstructions and debris, and all equipment access/

control panels are in place. Unit must be installed with

the proper clearances as listed in Figure 1 (page 4).

√ Verify that the duct work is sealed to prevent air leakage.

√ Verify that the line voltage power leads are securely

connected and the unit is properly grounded. Check

the condenser fan to make sure it turns freely.

√ Verify the thermostat is wired correctly and installed

in a proper location. Make sure the low voltage wires

are securely connected to the correct leads on the low

voltage terminal strip.

√ Verify that the power supply branch circuit overcurrent

protection is sized properly.

Start-Up Procedure

NOTE: The control circuit thermostat may consist of an

anti-short cycle timer that will not let the compressor re-

start before 3 - 5 minutes have elapsed.

1. Set the system mode to OFF and the temperature

mode to its highest setting.

2. Turn power on at the disconnect switch.

3. Set the system mode to ON or COOL.

4. Set the temperature mode below room temperature.

Verify that the indoor blower, outdoor fan, and

compressor energize and the cooling function starts.

5. Verify the discharge air grilles are adjusted and the

system air is balanced.

6. Verify the duct work has no air leaks.

7. Verify the condensate drain is installed correctly and

functions properly.

8. Set the temperature mode above room temperature.

The unit should stop.

9. Instruct the homeowner on unit and thermostat operation

and ﬁlter servicing.

Air Circulation

Leave the thermostat system mode on OFF, and set the

fan mode to ON. Blower should run continuously. Check

the air delivery at the supply registers and adjust register

openings for balanced air distribution. If air is insufﬁcient,

examine the ductwork for leaks or obstructions. Set the

thermostat fan mode to AUTO. The blower should stop

running.

System Cooling

Change the thermostat’s system mode to COOL and

the fan mode to AUTO. Set the thermostat temperature

selector below the existing room temperature. Allow the

cooling system to operate for several minutes and check

for the discharge of cool air at the supply registers.

COMPONENT FUNCTIONS

High Pressure Switch (HPS)

A high-pressure switch is factory-installed and located in

the liquid line internal to the unit. The switch is designed

to protect the system when very high pressures occur

during abnormal conditions. Under normal conditions,

the switch is closed. If the liquid pressure rises above

575 psig, the switch will open and de-energize the unit.

The switch will close again when the liquid pressure

decreases to 460 psig.

Low Pressure Switch (LPS)

A low-pressure switch is factory-installed and located in

the suction line internal to the unit. The switch is designed

to protect the compressor from a loss of charge. Under

normal conditions, the switch is closed. If the suction

pressure falls below 5 psig, the switch will open and de-

energize the unit. The switch will close again when the

suction pressure increases above 20 psig.

AIR CONDITIONER MAINTENANCE

WARNING:

To prevent electrical shock, personal injury,

or death, disconnect all electrical power to

the unit before performing any maintenance

or service. The unit may have more than one

electrical supply.

Proper maintenance is important to achieve optimum

performance from the air conditioner. The ability to properly

perform maintenance on this equipment requires certain

mechanical skills and tools. If you do not possess these

skills, contact your dealer for maintenance. Consult your

local dealer about the availability of maintenance contracts.

Routine maintenance should include the following:

• Inspectandcleanorreplaceairltersatthebeginning

of each heating and cooling season, or more frequently

if required.

• Inspectthecondensatedrainandoutdoorcoilatthe

beginning of each cooling season. Remove any debris.

Clean the outdoor coil and louvers as necessary using

a mild detergent and water. Rinse thoroughly with water.

• Inspecttheelectricalconnectionsfortightnessatthe

beginning of each heating and cooling season. Service

as necessary.

CAUTION:

The unit should never be operated without a

ﬁlter in the return air system. Replace disposable

ﬁlters with the same type and size.

• Donotattempttoaddadditionaloiltomotorsunequipped

with oil tubes. The compressor is hermetically sealed

at the factory and does not require lubrication.
